isdirected moreparticularly to improvements for-feeding successiveportions of strip material. --The mechanism of theinvention is directedto improvements in feeding devices adapted for feeding successivesections of various materials but is particularly adapted for feedingflexible yield'able material such asleather or the like.

The. mechanism is characterized by means which is movable in rearwardand forward feeding directions and is so constructed and arranged thatas the said means moves forwardly the material being fed is impingedwhile when moving rearwardly the material is released.

With the foregoing and various other novel features and advantages andother objects of my invention as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction and in the combination and arrangement of parts as willbe hereinafter more particularly pointed out in the claim hereuntoannexed and more fully described and referred to in connection with theaccompanying drawings wherein:

Fig. 1 is a plan view of feeding mechanism embodying the novel featuresof the invention;

Fig. 2 is a sectional elevational view on the line 2-2 of Fig. 1;

Fig. 3 is a side elevational view of the forward end of the mechanismshown in Fig. 1;

Fig. 4 is a plan view of one of the feed fingers of the mechanism; and

Fig. 5 is a sectional elevational view, at an enlarged scale, on theline 55 of Fig. 2.

Referring now to the drawings more in detail, the invention will befully described.

Elongated side rails 2 are provided which are transversely spaced andhave therebetween a sheet 4 such as metal for supporting a length ofmaterial which is to be fed from the rear right hand end of themechanism to the left hand or forward end thereof.

Bearing brackets 8 extend upwardly from forward end portions of therails 2 and have a transverse operating shaft Ill oscillatable therein.

The side rails may be supported by a machine to which successiveportions of material are fed and the shaft I0 may be oscillated fromsaid machine or by any suitable means in timed relation therewith. As anexample, the mechanism may be used with a punch press which includesmeans for cutting off or operating on successive portions of materialfed thereto.

Slide blocks 14 are slidable back and forth in elongated ways 16provided on adjacent inner sides of the railsat forward ends thereof.

1 Claim. (Ci. 2712.5)

These blocks M are provided with slots l8 which converge relatively andupwardly, see Fig. 2.

A feed member 24 extending transversely between the rails 2 hasforwardly and rearwardly extending arms 26 and 28. Pins30 fixed to andextending outwardly from arms 26 and 28 are disposed in the slots I8 ofthe slide members M. The member 24 is supported by the blocks 14 whichare slidable in the ways IS.

A lug 32 extends upwardly from the feed member 24 and is provided with apin 34.

A lever 36 fixed to the shaft H) has a slot 38 in the lower free endthereof in which the pin 34 is received, see Fig. 5.

As the shaft I0 is oscillated in opposite directions so that lever 36 isswung back and forth, the blocks through member 24 are moved back andforth in the ways therefor.

A lever 40 may be fixed to shaft II) which may be connected to operatingmeans for operating the mechanism.

Feed fingers 42 are secured to forward ends of arms 26. These arepreferably in the form of circular discs having relatively sharpperipheral edges for impinging the material being fed. The fingers maybe turned in new positions to present unworn portions for impinging thematerial.

A web of material may be laid on member 4 for feeding the sameforwardly. As the operating shaft is oscillated, the feed member ismoved back and forth it being supported by the blocks which are slidablein the ways.

The slot and pin arrangement of the blocks and feed member is such thatas the feed member moves from its rear position in a forward feedingdirection, the fingers tilt downwardly to engage and slightly impingethe material being fed.

The material is fed forwardly as the feed member moves to the left andwhen said member reaches the end of its stroke and is to move to theright, the pin and slot connections cause the fingers to immediatelyelevate and thereby disengage the material.

In this way as the feed member moves forwardly and rearwardly thefingers engage and feed the material and then release it wherebysuccessive portions of the material are fed forwardly.

The invention may be embodied in other specific forms without departingfrom the essential characteristics thereof. Hence, the presentembodiments are therefore to be considered in all respects merely asbeing illustrative and not as being restrictive, the scope of theinvention being indicated by the appended claim rather than by theforegoing description, and all modifications and variations as fallwithin the meaning and purview and range of equivalency of the appendedclaim are therefore intended to be embraced therein.

What it is desired to claim and secure by Letters Patent of the UnitedStates is:

Apparatus for feeding successive portions of material'fcjomprising incombination, elongated horizontal side rails and an elongated materialsupport having opposite longitudinal side portions secured to lowerportions of said rails holding the rails in transversely spacedrelation. brackets secured to and extending upwardly from said railshaving a shaft oscillatable therein. inner adjacent sides of said railsprovided with longitudinal ways disposed longitudinally thereof,elongated blocks slidable in said ways having elongated slots inopposite ends thereof relatively converging inwardly and upwardly, anelongated transverse feed member extending between said side railshaving elongated side arms extending forwardly and rear'wardly thereofand disposed adjacent and parallel to said side rails, pins extendingfrom forward and rear ends at outer sides of said side arms disposed inthe slots of said blocks, said slots and pins arranged for swinging ofsaid feed member relative to said '4 blocks and rails on an axistransverse to said side rails to move forward ends of the side arms ofsaid feed member up and down towards and away from said support, a leverfixed to said shaft having an end depending therefrom, 9. lug extendingupwardly from said feed member. pin and slot connections provided on theend of said lever and lug operatively connecting said lever to said icedmember whereby said feed member REFERENCES CITED The followingreferences are of record in the file of this "patent":
